While cornfields are plentiful in many areas, making a good sunset picture with them is a bit more challenging. Finding a field at a higher elevation that the western horizon is a good start. Then finding the right cornstalks to include in the image is the next challenge. Then position the sun to peak through the stalks just as it reaches the horizon.
